The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud engineered for the VMSS960804CNAA gas furnace and compatible Goodman/Amana models. This precision-drilled brass orifice meters the exact flow of natural gas into each burner, setting the flame size and the furnace's rated input BTU. Correct orifice sizing is essential for clean, efficient, and safe combustion.
Orifices can become damaged during burner service, clogged with debris, or lost during a fuel conversion. An incorrect or obstructed orifice causes poor flame, sooting, delayed ignition, or improper input rate. This exact-match replacement restores factory-spec fuel metering for natural gas.
OEM vs. Generic: The genuine Goodman orifice is drilled to the precise diameter matched to this furnace's manifold pressure and BTU rating. A generic orifice with even a slightly different bore changes the firing rate and can create unsafe combustion. For a fuel-metering part, OEM is the only safe choice.
Install difficulty: Moderate (technician recommended). Shut off gas and power, remove the manifold or burner, unthread the old orifice, and install the new spud without over-tightening. Verify manifold pressure and flame after install — about 20–30 minutes.
